VICTOR PETERSEN, or OMAHA, ,NEBRASKA Doon srLnNcnR nnvrcn Application filed February 18, `193.0. Serial No. 429,356.

This invention relates to door'silencers and has particular relationto a device adapted for use primarily in connection with doors within a dwelling house.

Anobject of the invention is to provide a means whereby noises attendant, as heretofore practiced, upon the opening and closing of doors willbe eliminated.

Another object of the invention is to provide a device adapted for the above described purposes which may be installed within a door opening and particularly in alignment with a door stop in a manner whereby the clothing of persons passing through the door I opening will not become caught upon the device.

A further object of the invention is to porvide adevice which is economical in construction, easy of installation and certain of opi eration.

' Other and further objects kand advantages of the invention will be runderstood from the following detailed description, reference being had to the accompanying drawings in which:

Figure k1 illustrates a `fragmentary horizontal sectional view of a door jamb, its casing and a door, certain partsv thereof being broken away, and showing the new device inposition of use, the latter being in section. y

Figure 2 is a side elevation of the jamb and having the new device applied to the stop therefor, the view being taken at right angles to the showing in Figure 1.

Figure 3 is a longitudinal sectional View of the new device. Q

y Figure 4 is an end view thereof, and

Figure 5 is an end view opposite to the view and showing in Figure 1.k

Referring to kthe drawings wherein like 'numerals of reference indicate like or corresponding parts throughout the several views7 y10 indicates a door jamb and 11 the o side casings thereof. In accordance with the conventional practicel the fixtures for the door opening and the door 12 includes a door stop 13, within which'the new device 14 is yadapted to be positioned in a manner whereby one of the side edges is flush with thestop 13, and

also the front thereof is flush with the edge of the stop.

' The new device comprises a'body portion 1.5, which is provided with a front flange 16, and ya rear liange 17, such flanges being bent substantially at right angles'to saidbody portion 15.

Intermediate said flanges, a cylindrical member 18 is carried. The cylinder 18 is hollow land is adapted tov be retained between said `flanges by any suitable means, such as by means of an indented concentric shoulder 19 formed upon the flange '16 and by .means of providing a shoulder 2O upon the member 18, said shoulder being adapted to be received within an aperture 21 formed through the flange 17.

An aperture 22 is formed through the flange' 16 and is adapted'to` snugly receive a plunger 22', the latter being provided with a shoulder 28 for preventing a too great sliding movement ofisaid plunger' within said aperture in a manner whereby rthe said par-ts would become disengaged.

The plunger 22 is provided with a rubber bumper 24 and is adapted to be' normally urged outwardly of the device by means of a spring E25 carried within the hollow cylindri- Cal member 18.

A cap 26 is threadedly received within 'the cylinder 18 in a manner whereby the spring 25 is prevented from outward movement.

The cap 26 is provided with a bit slot 27 fory the reception of a screw driver for the purpose kand function of adjusting the tension of the spring 25 to suit the individual requirements .of a door. A

lIn the .operation .and practice of the invention, the device is .preferably installed, flush with a stop 13 as shown in the drawings and bolt of the lock Vor keeper mechanism is received within the strike, the latter being sen cured to the jamb, that the normallyoutwardly urged bumper 24 will register against the door l2 in a manner whereby said bolt will firmly engage the strike, thereby preventing rattling noises of the doorsuch as is occasionedby draughts of air, and the like.'

In operation, and assuming that the door l2 is large or of heavy material such as oak, l

formed of western pine, the tension ofthe spring 25 may be adjusted to suit anyy partic-l Y ular condition required.

From the foregoing description, it is vplunger in the tube having a'reduced and socketed end received through the opening anda shoulder to engage the stop shoulder, a resilient tip inthe socket and spring means in the tube to force the plunger outwardly.

In testimony whereof, I have affixed my signature.

. VICTOR PETERSEN.

thought to be obvious Lthat a door silencer con-V structed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it Ves may be assembled and operated, and it will also be obvious thatmy invention is susceptible of some change and modification without departing from the principle and spirit thereof, and for this reason I do not wish tov be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out myinvention in practice, except as herein claimed.

"IVVhat is claimed is l. A door silencer comprising a casing composed of a plate and anges on the plate, one of the flanges being perforated and having a pressed-in part around the perforation, a tube between the flanges registering with the perforationand confined by said pressedin part, and a yieldably-pressed plunger in and projecting from said tube and perforated Hangs.

2. A door silencer comprising aplate having spaced flanges, one of said flanges having an. opening, Va tube having a reduced and shouldered end engaged in said opening and against Vthe flange, and a yieldablyepressed plunger in and projecting from said tube.

3.l A door silencer comprising a plate havg ing flangeswith Valined openings, a tube held between the flanges registering with the openings, a plunger in the tube projecting through one opening, a spring inthe tube behind the plunger, and a cap threaded in the opposite end of the tube through the opening in the other flange and acting to adjust thevtension of said spring.

4. A doorsilencer comprising a plate having`fianges, means lto secure the plate to a door jamb, a tube between the flanges, one of the flanges having an opening of less diameter than the tube forming a stop shoulder, a
